The only exception to this rule is if power is removed from the unit,
allowing it to cool down. This can occur due to: extended power
outages, unplugging the amplifier from the wall during a vacation; or
by leaving the amplifier in sleep mode rather than in standby. In these
cases you should expect a brief warm-up period before the amplifier's
sound quality is at its best. (Fortunately, you will never have to repeat
the full 300 hour break-in period.)
PLACEMENT CONSIDERATIONS
For your protection, review "Important Safety Instructions" above
before you install your amplifier.
Your VIOLA Bravo power amplifier is specifically designed to
accommodate a wide range of installation options. These amplifiers
may be placed on the floor, near the loudspeakers they drive. They
may also be located on shelves provided the shelves are sturdy
enough to bear the weight of the amplifier and have sufficient room for
proper ventilation. The sophisticated ventilation system employed by
the Bravo power amplifier will maintain optimal operating
temperatures in the output stage of the amplifier even when they are
stacked one above another.
However, if you have a choice in your design, locating each amplifier
near its respective loudspeaker is usually best. This approach
minimizes the length of the speaker wires, and necessitates longer
interconnecting cables from the preamplifier to the power amplifier.
The advantage to this strategy lies in the fact that the interconnecting
cables carry low-current signals that are more readily transmitted over
distances with great accuracy than are the necessarily high current
signals required by loudspeakers.
Note that adequate clearance for the AC cord and connecting signal
cables must be left behind your amplifiers. We suggest leaving at least
six inches (15 cm) of free space behind your amplifier so all cables
have sufficient room to bend without crimping or undue strain.
The Bravo power amplifier was designed to use both active and
passive cooling strategies. This highly efficient system features a
forced air cooling system to maintain optimal operating temperatures
under a wide range of conditions. This combination of passive and
active cooling is accomplished by fans running in conjunction with an
efficient system of heat sinks. Two ultra low-noise fans provide cooling
